ci: bump rust client publish version

[dev-jodee]

Summary

• Bump the Rust client crate subscriptions to 0.1.1 because 0.1.0 already exists on crates.io
• Read the subscriptions package version explicitly in the Rust publish workflow instead of relying on Cargo metadata package order
• Add an early crates.io availability check so already-published versions fail before trusted publishing auth/publish

Test Plan

• cargo check -p subscriptions --locked
• cargo publish --dry-run --locked --allow-dirty from clients/rust
• pnpm exec prettier --check .github/workflows/publish-rust.yml
• YAML parse check for .github/workflows/publish-rust.yml
• pre-push hook: format check and lint check
